    Episode 177: The Case of the Missing Dark Matter, with Guo Chi

    Episode 177: The Case of the Missing Dark Matter, with Guo Chi

    Dark matter vastly overshadows ordinary matter in our universe. Wherever astronomers turn their telescopes they find galaxies dominated by dark matter. But all that changed recently with the first discoveries of dwarf galaxies suspiciously deficient in dark matter. To make sense of this baffling finding and how it relates to our Milky Way’s own local dwarf galaxies, today we’re joined here at The Star Spot by study lead Professor Guo Qi from the Chinese Academy of Science.

    Episode 176: Second Genesis, with Jay Melosh

    Episode 176: Second Genesis, with Jay Melosh

    If we should find creatures crawling around Titan or swimming under the ice sheets of Europa or Enceladus, they will almost certainly turn out to be the result of a second genesis, those creatures truly alien in the most profound sense. That startling conclusion follows from a series of groundbreaking simulation that found it exceedingly unlikely that life can be successfully transferred between the worlds of our solar system. Today we’re joined here at The Star Spot by geophysicist Jay Melosh.

    Episode 175: The Truth is Out There (at the University of Manitoba)

    The University of Manitoba has just acquired the largest collection of UFO related material. Whether you’re intrigued by the phenomenon of belief or you believe in the phenomenon, the extraordinary human effort to address the UFO question is worth our attention, argues Shelley Sweeney, Head of Archives & Special Collections at the University of Manitoba, who joins us here at The Star Spot.

    Episode 174: Fuzzy Dark Matter, with Lachlan Lancaster

    Episode 174: Fuzzy Dark Matter, with Lachlan Lancaster

    Quantum mechanics is strange. Until recently we could comfort ourselves with the belief that its odd properties were safely confined to the world of the microscopic. But what if quantum mechanical effects were suddenly magnified to cosmological scales. That’s a possibility, according to a new theory of dark matter known as fuzzy dark matter. Today we’re joined here at The Star Spot by Lachlan Lancaster, co-author of a new paper that sheds light on these questions.

    Episode 173: Discovering an Ancient Oasis, with William Rapin

    Episode 173: Discovering an Ancient Oasis, with William Rapin

    Welcome to Sutton Island, consisting of shallow lakes filled with salts and minerals. It’s a common vista on this world, and while the world in question is not our home, ancient Mars may well have been someone’s home. Today we’re joined here at The Star Spot by William Rapin, with reports from the latest discoveries of the Mars Curiosity rover and why one of the Principal Investigators of NASA’s Viking mission is now convinced we found life on Mars back in the 1970s,

    Episode 172: The Hubble Not-So Constant

    Episode 172: The Hubble Not-So Constant

    The Hubble constant, which measures the expansion rate of the cosmos, may not be a constant after all, and if that’s true it means we’re missing something big in our understanding of the universe. Today we’re joined here at The Star Spot by Sherry Suyu, who leads the aptly named H0LiCOW project which uses the phenomenon of gravitationally lensed quasars to measure the expansion rate of the universe.
